Abstract: An arrangement for sensing the operating condition of an alternating current machine (10) employs a Hall switch (32) on the stator (12) which is subjected to the alternating magnetic field established during operation. The Hall switch (32) has a magnetic field strength threshold below which it will not be actuated. During normal operation of the machine, the alternating field strength will cyclically exceed the switch threshold, thereby generating a series of pulses at the frequency of alternation of the field. Should the field strength decrease as a result of overload of the machine, or a decrease in line voltage, to a level below the threshold level of the switch (32), the pulse output of the switch will cease. Circuitry (34, 36, Q 1 ) responsive to the absence of periodic pulses actuates an indicator circuit (38) to warn of the faulty operation.

Abstract: A semiconductor processor for signals such as are conveyed by fibre optics wherein the processor structure accommodates lattice mismatch and minimizes the effect of misfit dislocations. The structure permits using materials having favorable absorption properties at the 1 micrometer wavelength of optical signals. A binary semiconductor is employed with graded regions produced by adding a different third ingredient in two places so that a wide band optically transparent emitter with a graded base and graded collector are provided. The ingredients impart a strong absorption in the optical signal wavelength together with superior semiconductor carrier transit time. A structure for a silicon and germanium oxide based optical signal fibre uses a GaAlAs emitter, a base that is graded to Ga 25 In 75 As at the collector and then back to GaAs at the substrate.

Abstract: A process for regenerating a resin, comprises the steps of dissolving a waste resin in an organic solvent to provide a resin solution, mixing the resin solution with a liquid of normal temperature, the liquid being immiscible with the solvent, scarcely dissolving the resin, and having a specific gravity smaller than that of the solvent and larger than that of the resin, thereby separating the resin from a mixture of the resin solution and the liquid, and recovering the resin. The liquid may have a temperature higher than the boiling point of the solvent. In this case, the solvent evaporation takes place together with the resin separation. The evaporated solvent is cooled later for recovery of the solvent.

Abstract: In a charge transfer device (Figure 1) an auxiliary charge store and gate (G A ) is provided adjacent to the devices input (9) - ie adjacent to the device source (S), or to the device first store (beneath G s ), or to both. In order to provide background subtraction, charge is transferred back and forth. under auxiliary gate control, between the device input (9) and the auxiliary store (beneath G A ) many times during each period of charge integration and a fixed increment of charge is removed for each such transfer. The total charge subtracted each integration period is dependent on the number of transfers; this latter is determined by the frequency of a control signal applied to the auxiliary gate (G A ). This frequency may be set manually, or may be servoed by output circuitry in order to set an automatic adaptive threshold.
